rclone is a command-line program to sync files and directories to and from different cloud storage providers. Prior to 1.75.1, rclone serve s3 configured with --auth-proxy but without --auth-key allows authPairMiddleware to register any client-chosen accessKeyID with an empty ws.s3Secret. gofakes3 then verifies the request’s SigV4 signature against that same empty secret, while Server.auth passes the access key identifier as both the user and authentication value to the proxy without an independent per-identity secret. An unauthenticated network attacker can therefore choose an arbitrary access key, sign with an empty secret, and reach whatever backend the auth-proxy script resolves for that identity. This issue is fixed in version 1.75.1.Show less

Traefik is an open source HTTP reverse proxy and load balancer. From 2.11.0 until 2.11.57 and 3.7.13, the HTTP/3 entrypoint ConnContext does not call service.AddTransportOnContext, so kerberosRoundTripper uses a shared backend transport instead of a transport dedicated to each frontend connection. With HTTP/3 enabled, a backend using connection-bound NTLM or Negotiate authentication, and backend keep-alive, an unrelated client can reuse a backend connection authenticated for a victim, read victim-only data, and act as that victim without the victim credentials. This issue is fixed in 2.11.57 and 3.7.13.Show less

MantisBT is an open source bug tracker. Versions 2.28.3 and earlier contain a critical authentication bypass in the SOAP API's mci_check_login() function. Any user knowing any valid cookie_string can authenticate as any other user (knowing their username), including the administrator, without knowing the target's password. The vulnerability is exploitable with zero prior access on default MantisBT installations because self-registration is enabled by default ($g_allow_signup = ON). A self-registered user can use their own cookie_string (readable from their browser's MANTIS_STRING_COOKIE cookie after login) to impersonate the administrator via the SOAP API. The REST API is NOT affected. The REST API's AuthMiddleware derives the username server-side from the API token or session cookie, so the username cannot be spoofed. The Web UI is NOT affected. The Web UI authenticates via PHP session cookies (PHPSESSID) and validates the MANTIS_STRING_COOKIE against the logged-in user through auth_is_cookie_valid(). The username is derived server-side from the cookie, not supplied by the client. Version 2.28.4 contains a patch. No known workarounds are available.Show less

Parse Server versions <= 8.6.87 and >= 9.0.0 < 9.10.1-alpha.7 contain an authentication bypass in the built-in LDAP authentication adapter. The adapter forwarded the client-supplied password to the directory without verifying that a password had been supplied, and treated any non-error response from the directory as proof of authentication. A zero-length credential turns an LDAP simple bind into the unauthenticated authentication mechanism described in RFC 4513 section 5.1.2, which some directories (including Active Directory in its default configuration) answer with success while mapping the connection to anonymous. As a result, an unauthenticated attacker who knows a directory username can obtain a valid session token for that account, resulting in account takeover. Only deployments that enable the LDAP authentication adapter are affected, and deployments whose directory refuses unauthenticated simple bind (such as a stock OpenLDAP configuration) are not exploitable. The issue is fixed in 8.6.88 and 9.10.1-alpha.7, which require the password to be a non-empty string and reject the request before contacting the directory.Show less

Several Newfold plugins are vulnerable to Authentication Bypass. The vulnerability exists because the plugins bundle the wp-module-data module. In the module, the `authenticate()` method — registered on the `rest_authentication_errors` filter and therefore evaluated for every unauthenticated REST API request — performs an HMAC-style Bearer token comparison that degenerates when `HiiveConnection::get_auth_token()` returns `false`: PHP coerces `strrev(false)` to `strrev('')`, collapsing the secret salt to the publicly known constant `hash('sha256', '') = e3b0c44...`, while all remaining hash inputs (HTTP method, request URL, raw request body, and the `X-Timestamp` header) remain fully attacker-controlled. This makes it possible for unauthenticated attackers to compute a valid Bearer token entirely offline, pass the token equality check, and have `wp_set_current_user()` invoked against the first administrator returned by `get_users(['role' => 'administrator'])`, granting full administrator-level access and enabling arbitrary REST API operations such as creating new administrator accounts and achieving complete site takeover. Vulnerable versions are WP Plugin Crazy Domains (<= 2.5.2), WP Plugin Web (<= 2.3.4), WP Plugin Hostgator (<= 3.1.0), WP Plugin Bluehost (<= 4.17.1). The affected module is vulnerable in versions up to, and including, 2.9.4.Show less

The Next-Cart Store to WooCommerce Migration plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 3.9.8 via the `NCWM_Kitconnect::run()` function. This is due to the plugin registering the `/wp-json/next_cart/v1/migration` REST route with `permission_callback` set to `__return_true` and relying on a hardcoded fallback value of `__token__` in `get_option('nextcart_token', '__token__')` when the `nextcart_token` option has not yet been written to the database. This makes it possible for unauthenticated attackers to bypass authentication to the migration endpoint by supplying the literal string `__token__` as the token, gaining access to privileged handlers that pass attacker-controlled SQL directly to `$wpdb->query()` and `$wpdb->get_results()` — enabling arbitrary SQL execution including administrator account creation — and pass an attacker-controlled path to `unlink()`, enabling arbitrary file deletion and full site takeover. The hardcoded fallback is reachable whenever the `nextcart_token` option has not yet been populated, which occurs after WP-CLI, network, or programmatic plugin activation without a subsequent authenticated `wp-admin` visit, as token generation is deferred to `admin_init` via `register_settings()`.Show less
